SPOILER ALERT: If you haven't read If I Stay, don't read this review.Gayle Forman has done it again. Where She Went is a completely different book than If I Stay but I still adored it. In fact, I couldn't put it down. I read straight through this one. Adam and Mia's story only just begun with If I Stay.It's been three years since Adam has seen Mia. Three years since she walked out of his life and took all the joy with her. Now, by chance or fate, he is in New York for one night only and he runs into her. It's finally time to find out where she went and where she's going.Originally, I didn't think If I Stay needed a sequel. I kinda liked that it was left open at the end. Of course, when I started Where She Went, I changed my mind. Adam and Mia's story was only part of If I Stay. Where She Went told the whole thing.Where She Went is told from Adam's point-of-view and it was pretty heartbreaking. His whole life changed with the accident too but nobody seemed to notice or care. When Mia left, it just got worse. It wasn't anywhere near as devastating as If I Stay but I still found myself crying at parts.Overall, Where She Went is a brilliant follow-up to If I Stay. Fans of If I Stay will not be disappointed. =]
